Abstract (en)
A manufacturing method for an evaporator (1) made of aluminum alloy. First, a three-layer aluminum alloy plate having a core (21) made of Al-Mn alloy, a sacrifice anode layer (22) made of aluminum alloy which is electro-chemically base with respect to the core (21) and clad on one side of the core (21), and a brazing layer (23) made of Al-Si alloy and clad on the other side of the core (21) is uniformly rolled to be work-hardened. Next, the thin work-hardened aluminum alloy plate (20) is bent to form a tube (2) so that the sacrifice anode layer (22) is disposed outside the tube (2) to face air and the brazing layer (23) is disposed inside the tube (2) to face refrigerant. Then, plural tubes (2) and outer fins (4) are alternately laminated and are integrally brazed to tanks (5-7) to form the evaporator (1). As a result, a thickness of the tube (2) is reduced without deteriorating corrosion resistance of the tube (2), thereby decreasing a weight and a size of the evaporator (1). <IMAGE>
